I'm not too sure who Boston is looking to move with only Debrusk name being brought up couple weeks ago in a recent threat that suggest Bruins are not interested in signing him.
In Vancouver, Benning has chewed out Virtanen, which suggests he might be available,
Debrusk is more offensive then Jake, but smaller and not as physical. If the Canucks make a trade like this, we are losing a lot of hitting as Jake averaged around 6 hits per game during the playoffs. Debrusk is more around the offensive side but not nearly as physical.
Another player Boston might want to target is maybe Adam Gaudette who is from the Boston area and maybe the Bruins want to bring in a player that is from Boston? who knows, but I don't think Boston is looking to move any top 4 dmans with Chara not playing much longer in the NHL even though he said he's willing to return.
